Oculus Hand Tracking
“Hand tracking” via link is considered a developer feature by Meta, so there’s a few hoops you need to jump through.
This is only tested with a Quest 2 and a Quest Pro. It probably doesn’t work with a Rift S.
- Enable hand tracking in your headset - documentation
- Set up your account as an Oculus Developer account - documentation - you do not need to allow USB debugging or install the ADB drivers
- Restart the Oculus PC software
- Enable ‘Developer Runtime Features’ under Settings -> Beta. If you don’t see the option yet, try again later - it can take a few hours
- In HTCC settings, set ‘hand tracking source’ to ‘OpenXR Hand Tracking’
Virtual Desktop
If you choose to use Virtual Desktop instead of Link/AirLink:
- you must use VDXR
- turn on ‘send tracking data’ so that your PC - and HTCC - receive the hand tracking data
- leave hand tracking in Virtual Desktop turned on
- if you have a Quest Pro, as of 2024-11-26, Virtual Desktop can not enable hand tracking unless face and body tracking are also enabled on your headset
Sleep/wake
Hand tracking and gesture recognition is not perfectly reliable; it will hopefully improve with future Oculus firmware updates.
HTCC reduces the changes of accidental clicks by:
- adding sleep/wake mode
- ignoring gestures unless you’re looking close to your hand
‘Wake’ hand tracking by waving your hand close to the center of your view. Tracking will ‘sleep’ for that hand after a few seconds of little movement.
The limits can be tweaked in the registry if needed.
FAQ
Why do pinch gestures require Oculus headsets?
The [XR_FB_hand_tracking_aim
] OpenXR extension is required, which is currently only supported by Oculus headsets.
Other headsets would work if other OpenXR runtimes add support for XR_FB_hand_tracking_aim
, or if other projects emulate it using [XR_EXT_hand_tracking
] or vendor-specific APIs. I am not aware of any projects doing this at present.
Standard OpenXR hand tracking via XR_EXT_hand_tracking
does not provide enough similar precise gestures.
